Abstract:
Today world is step-in 21st century. But still in major part of India cannot get 24 X 7 eclectic power supply.
Electrical power has become a prime necessity for any country for economic development. And power shortage
is a dominant problem, being faced by the most of the countries today. On the top of this, the conventional fuel
sources for power generation i.e. coal & oil deposits are fast getting depleted. The Obvious way out, is to shift
focus to renewable sources of energy and in country like India our village population & remote location load
always suffer by power cut or grid failure although they have enough potential to generate own power but due to
lake of technology they can‟t get 24 x 7 power supply to provide some solution of this problem we try to
develop smart grid Indian version.
Although more invention has to be carried out still in the use of non-conventional energy sources for
power generation to reach to most economic point, but every little effort in this direction may provide a solution
to power shortage problems. Hence the same topic was selected as a part of the curriculum. The goal of the
paper is to construct a micro smart grid which is capable of producing enough electrical power by using local
removable energy electrical power sources like wind, bio-gas, solar, current running hydro plan for the places
like remote places like villages
In this paper, we propose a decentralized framework named Micro Smart GRID to tackle grid resource
management a simulation study of operation and control of local generation & co-ordination with state grid in
case of normal operation or power islands in Micro Smart Grid environment.

Introduction:
The development of smart grid wills the future of grid system. It required advance technology, device&
management system to make the grid „Smart‟. The automation of the transmission and distribution system will
be critical for full smart grid development. While definitions Micro grid is essentially smaller version of the
lager electrical grid and design to serve localized electrical loads. Micro grid are develop around distributed
energy resources (DER) which provide power and make the micro grid self sufficient. Microgrid is typically
connected to a utility grid (state grid) but they have ability to isolate themselves from the grid when power
problem occurs and operate as a self-contained entity in an „islanding‟ mode. They are small and can vary size
from single village to small town. For the smart grid to maximize energy savings, we need buildings to work.
And further, the cost effectiveness of the smart grid as a whole will rely on the materialization of building
energy savings.
The smart grid is more than simply installing smart meters – by bringing an information technology to
the electric grid, we will develop numerous applications that use the devices, networking and communications
technology, and control and data management systems. Our nation‟s electrical grid is outdated and
overburdened. Infrastructure investments over the past decades have not kept pace with the growing demand
for electricity. In addition, the old grid has numerous problems including reliability and power quality,
transmission and distribution bottlenecks, as well as environmental concerns that require the integration of
renewable energy and distributed generation. This paper first provides an overview of the grid challenges and
then presents a critical review of the salient reliability impacts of the four smart grid resource types identified

above. We observe that an ideal mix of these resources that flattens net demand would eventually accentuate
reliability issues even further.

Meeting reliability challenges requires a grid-wide IT infrastructure that provides coordinated monitoring and
control of the grid. We then present an architectural framework for such IT infrastructure. The architecture is
designed to support a multitude of geographically and temporally coordinated hierarchical monitoring and
control actions over time scales ranging from milliseconds to operational planning horizon. Such capability is
necessary to take full advantage of the modern measurement technologies (e.g. PMUs) and control devices (e.g.
FACTS).The architecture is intended to serve as a concrete representation of a common vision that facilitates the
design and development of various components of the IT infrastructure and emergence of standards and
protocols needed for a smart grid As above shown is the economical scenario of the renewable energy sources in
India state of Maharashtra now, some of the basic fundamental need for the implementation of micro smart grid
in India at grass root level is as shown below the model and working of model as well as technical flow chart
wit explanation.

Barriers for Advance Renewable Energy Sources:
 Low return on investment (ROI)
 High first cost
 Lack of knowledge/awareness
 Lack of interest/motivation
 Decrease in comfort/convenience
 Limited product availability
 Perceived risk
 Consumer Education
 Direct Consumer Contact
 Advertising and Promotion
 Alternative Pricing
 Direct Incentives

Intelligent devices, such as smart meters, sensors and grid aware equipment.
Networking technology for two-way communications, including pathways like cable, Wi-fi or power
line carrier.
Advanced control and data management systems that provide automated decision-making on the
supply and demand sides, as well as meter data management systems.
Flexible: fulfilling customers‟ needs whilst responding to the changes and challenges ahead;
Accessible: granting connection access to all network users, particularly for renewable power sources
and high efficiency local generation with zero or low carbon emissions;
Reliable: assuring and improving security and quality of supply, consistent with the demands of the
digital age with resilience to hazards and uncertainties;
Economic: providing best value through innovation, efficient energy management and „level playing
field‟ competition and regulation.
Design Criteria of MSG (Micro Smart Grid)
The design criteria that would be employed to meet these performance specifications
must address the following key power system components or parameters:
1. End-Use Energy Service Devices
2. System Configuration and Asset Management
3. System Monitoring and Control
4. Resource Adequacy
5. Operations
6. Storage
7. Communications

Demand Response / Load Management
Demand response allows consumer load reduction in response to emergency and high load demand
conditions on the electricity grid. Such conditions are more prevalent during peak load or congested operation.
In a micro smart grid, real-time load information enables wider voluntary participation by consumers. Demand
response can be implemented through either automatic or manual response to use local power generation or use
state grid power for this management we use load forecasting model and real data base model for load
management which use to control load flow in micro smart grid system as well as provide control signal to
operation of local generation station.

Smart meters :
There is no single definition of smart metering. A smart-meter system comprises an electronic box and a
communications link. At its most basic, a smart meter measures electronically how much energy is used, and
can communicate this information to another device.
Two-Way Communication between the Meter and the Supplier - enabling a wider range of functions
known as Automated Meter Management. A further refinement of the AMM meter is an Interval Meter - a two-
way meter with a capability to store and communicate consumption data by time-of-use (e.g. half-hourly
intervals).they use communication with central control central by using different method like GSM, CDMA,
Wi-Fi, wireless, telephone etc.
Model of micro smart grid for rural India
As per figure we define the Indian model of micro smart grid. In typical Indian rural area or remote area
has major potential non-conventional energy sources are wind, solar, biogas, current hydro energy etc. which
can be utilize for local generation. The local load is typically connected to the state grid which is not much
reliable so by using new smart technology and local energy source we develop model to operation. For develop
this model we use major design of smart grid but our model is basically focus on reliability of power by using
maximum local non conventional energy sources.
This green energy also gives the carbon credit as well as annual additional income to the investor about Rs.11
0000 /year /1 MW.

As above shown in the folw char the system works like this its shows the folw of operation procuder for
the system we under stand this process step by step:
Step 1: when system starts it collet the data from the state grid like Voltage level (V), Frequency (f) , Power
factor , phase sequence will be check and feed to the local control center

Step 2: now it check the availablity of the local power so we get idea is local generation awalable or not it use
the local communication RTU for the communication and get data from the fild that how much power awalable
from the renawable nergy source

Step 3: it will compare is the local generation enough to feed the local demand .? if its not enough then it
will shwith ovet the loacl load on the state grid supply. And if its enough loacl generation awalable then it will
get in to further step.
Step 4: when many local generation awalable at that time control system find the optimum generation
solution so we can get enough and cheap as well as economical power for local suppuply
Step 5: when we get economical local genration then we swith over the local generation
Step 6: now system calcualte is the local generation enough to feed the local laod if its not neough then it
will share load with the state grid and acording to that it swith on the system.and if its enough then it will go
ahead.
Step 7: If local genration enough to feed loacl deman then it will swithc on the local genertion totall
Step 8: controlar check if gneration is additional mens more then local demad then it will communicate
the state grid and feed the state grid if is enough then it will go to step 4 and in additional genetion we get extra
revanue from selling power to state grid.
This way in close loop system this micro smart grid model works.
Operation of micro smart grid model: typically local load is connected to local substation which
connected to state grid. By atomized local substation and communicate load flow database with state grids and
according to that design load flow forecasting model. Which use full to operate the local power generator like
solar, wind, biogas, and current hydro. In day time we can use solar for healthy condition we use wind and bio
gas can be use for 24x 7. Current hydro can be use as availability of water. To switch on the local power
generation we have to establish local control system which operates by a single PC based monitoring, operating
& control system communication with state grid by using internet, GSM , CDMA or other communication
linkup.

Micro Smart grid will
 Increase sustainability of power in local level
 Provide adequate capacity to state grid
 Create uniform grid connection increase reliability
 Provide higher security and quality supply
 Enhance efficiency & lower economical & environmental effect.
 Support and co-ordinate future developments of lager gird & technology

Why large scale smart grid not started?
 Limited pilot experience
 Limited statically proof of benefit
 Uncertainty with investment and large investment

Conclusion:
For Indian economy rising fuel costs, underinvestment in aging infrastructure and climate change are all
converging to create a turbulent period for the electricity industry. A micro Smart Grid can benefit use of renewable
energy sources all while improving the reliability, security, and useful life of electrical infrastructure. Despite its
promise and the availability of most of the core technologies needed to develop the Smart Grid, implementation has
been slow. To accelerate development, state, county, and local governments, electric utility companies, public
electricity regulators, and IT companies must all come together and work toward a common goal.
